  • Method Details

    • copy

      public RelNode copy(RelTraitSet traitSet, List<RelNode> inputs)
      Description copied from interface: RelNode
      Creates a copy of this relational expression, perhaps changing traits and inputs.

      Sub-classes with other important attributes are encouraged to create variants of this method with more parameters.

      Specified by:
      copy in interface RelNode
      copy in class AbstractRelNode
      traitSet - Trait set
      inputs - Inputs
      Copy of this relational expression, substituting traits and inputs
    • deriveRowType

      public RelDataType deriveRowType()
      deriveRowType in class TableScan
    • register

      public void register(RelOptPlanner planner)
      Description copied from interface: RelNode
      Registers any special rules specific to this kind of relational expression.

      The planner calls this method this first time that it sees a relational expression of this class. The derived class should call RelOptPlanner.addRule(org.apache.calcite.plan.RelOptRule) for each rule, and then call super.register.

      Specified by:
      register in interface RelNode
      register in class AbstractRelNode
      planner - Planner to be used to register additional relational expressions
    • implement

      public void implement(GeodeRel.GeodeImplementContext geodeImplementContext)
      Description copied from interface: GeodeRel
      Callback for the implementation process that collects the context from the GeodeRel required to convert the relational tree into physical such.
      Specified by:
      implement in interface GeodeRel
      geodeImplementContext - Context class that collects the feedback from the call back method calls
